Pteris on the Terrace

We’ve long loved the fern genus, Pteris (pronounced terrace), but struggled for years to find any that were winter hardy here in Zone 7b. That changed with our 1996 Chinese expedition to Yunnan Province, and later a subsequent expedition by gardening friends to Sichuan Province. On both trips, high elevation collections of Pteris vittata were

Reticulation anyone?

We ran across this fascinating reticulated leaf form of the US native (every state east of the Mississippi) groundcover partridge berry (Mitchella repens) last week, when tromping through the woods near JLBG. We’ve taken a few cuttings that will be evaluated here for garden performance. In 60 years of botanizing, this is the first form

Thyme Flies, Thymophylla Flowers

We are in love with the long-flowering Thymnophylla pentachaeta var. pentachaeta ‘Laredo Gold’, which graces us with masses of gold flowers from spring through fall, in our sunny, dry rock garden. This Patrick McMillan collection comes from a population in Texas. Not only is this short-lived, southwestern US native reseeding perennial great in flower, but

Christmas in June

While doing some local botanizing recently, we ran across this fascinating form of our native Christmas fern, Polystichum acrostichoides. Not only was it more compact than any others in the area, with more “orderly” fronds, but it also showed none of the typical terminal spore production that would be expected this time of year. Since

Stunning Townhouse

Lagerostroemia faurei ‘Townhouse’ is looking great at JLBG this summer. This compact selection was named by the late J.C. Raulston, in addition to the taller, narrower cultivar L. ‘Fantasy’. Townhouse crape myrtle is also highly prized for its dark cinnamon bark…the darkest of any crape myrtle we know. Our oldest specimen is now 35′ tall

The Thrilla of Cyrilla

If you’ve been following our blog for a while, you’ll remember we wrote about this amazing native shrub/small tree last summer. Well, it’s cyrilla time again in the gardens at JLBG, when every branch of this amazing semi-evergreen erupts with racemes of small white flowers, inviting all insects in the neighborhood to stop by for

Oldham’s Azalea

Few gardeners have probably grown the Taiwanese Rhododendron oldhamii, but this little-known species has become one of the most important azaleas in American horticulture. Here it is flowering in our garden in late spring. Then will be followed by a late summer/fall rebloom. Rhododendron oldhamii was named for British plant explorer Richard Oldham (1837-1864). Here’s
